Readme
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Test if a finite numeric value is an odd number.
npm install @stdlib/math-base-assert-is-odd
var isOdd = require( '@stdlib/math-base-assert-is-odd' );
Tests if a finite numeric
value is an odd number.
var bool = isOdd( 5.0 );
// returns true
bool = isOdd( -2.0 );
// returns false
bool = isOdd( 0.0 );
// returns false
bool = isOdd( NaN );
// returns false
The function assumes a finite number
. If provided positive or negative infinity
, the function will return true
, when, in fact, the result is undefined. If x
can be infinite
, wrap the implementation as follows:
function check( x ) {
return (
x < Infinity &&
x > -Infinity &&
isOdd( x )
);
}
var bool = check( Infinity );
// returns false
bool = check( -Infinity );
// returns false
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var isOdd = require( '@stdlib/math-base-assert-is-odd' );
var bool;
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = round( randu()*100.0 );
bool = isOdd( x );
console.log( '%d is %s', x, ( bool ) ? 'odd' : 'not odd' );
}
@stdlib/math-base/assert/is-even
: test if a finite numeric value is an even number.This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
